Product Description:

The MDD090C-N-020-N2M-110GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it delivers closed-loop rotary motion to axes that require precise positioning, velocity control, and repeatability in automated equipment. The unit follows the 090 frame size and uses a standard housing with a balanced rotor arrangement, making it suitable for general-purpose machinery where vibration must be controlled. This configuration is commonly used on feed axes, transfer systems, and similar motion applications that depend on consistent servo response.

The rotor is statically balanced, and a centering diameter of 110 mm aligns the flange to mating hardware without shims. A continuous standstill torque of 10.4 Nm allows the drive to hold loads without overheating when the shaft is locked. The nominal operating speed is 2000 rpm, matching drive controllers that supply the required electrical frequency for this pole count. Position feedback is generated by an integrated multi-turn absolute encoder, so the controller retains the true mechanical angle after power loss. Power and feedback conductors exit on side B, and the keyed industrial connector allows connection without opening the motor enclosure.

A blocking brake rated for 6.5 Nm secures vertical or suspended loads whenever the drive is disabled, while the primary motion loop receives high-resolution position data through digital servo feedback (DSF). The shaft uses a plain shaft profile that mates to couplings without keys, and it is equipped with a shaft seal to limit lubricant egress and dust ingress at the output end. The unit has a standard drive-side shaft end only and follows length code C for its electromagnetic stack. That motor geometry supports the torque and speed values noted above while keeping the housing compact for enclosed machine layouts.
